Terminal emulator with splitting built in
| Action | Shortcut |
|---|---|
| Split Vertical | ctrl + shift + E |
| Split Horizontal | ctrl + shift + O |
| Cycle tabs | ctrl + shift + P/N |
| Close focused | ctrl + shift + W |
Personally, I find the default icon to be hideous.
Edit /usr/share/applications/terminator.desktop replace existing icon with org.gnome.Terminal or whatever you prefer
